Аннотация

По измерениям тяжелых (M/q > 3) ионов на спутнике Фобос-2 было обнаружено, что плотность этих ионов в центральном плазменном слое ареомагнитного хвоста пропорциональна плотности протонов солнечного ветра, обтекающего планету. При сравнении данных спутника ISEE-2, измерявшего ионы в околоземном плазменном слое вблизи нейтрального слоя, с данными по солнечному ветру, полученными на спутнике ISEE-3, было установлено, что плотность протонов околоземного плазменного слоя также пропорциональна плотности протонов солнечного ветра. Анализ баланса магнитного и плазменного давлений в солнечном ветре и внутри хвостов магнитосфер Марса и Земли показал, что выявленные ранее корреляции являются следствием необходимого равенства давлений на границе магнитосферы и внутри магнитных хвостов планет.
